Our dear country Nigerian gained her independence in 1960 but before then,education has being in existence.Several changes and transformation has been occurred in our system during that time and now..This led to the write up curriculum development and evolution of education system.The transition of education system in 1954 change from 8-6-2-3 to 6-5-2-3 i.e 8 years in primary school, 6 years in secondary school,2 years at higher education and 3 years in the university change to 6 years in primary school, 5 years in secondary school, 2 years at higher education and 3 years in the university.Nigerians were more concerns about new policy of education and this led to 1969 Curriculum conference held in Lagos.More details are shown in the picture above....
